( Application filed February 25, 1925. Serial No. 11,598.

To all whom it may concern:

Be it known that I, ALFRED.H.'OELKEBS, a citizen of the United States, and a resident of Springfield, in the county of Greene and State of Missouri, have invented a new and Improved Roof Construction, of which the following is a full, clear, and exact description.

This invention relates to roof construction, and, while it is primarily designed as a flexible metal roof and combined running board for freight cars, it is also capable of application as a roof for building struc- I tures, and, hence, while I shall hereinafter refer to the same as a car roof structure,

it is to be understood that I use this language in its broadest possible sense to include any use to which the roof might be put. 1

The primary object of the "invention is to provide a roof construction in which the running board and the roof sheets are con] bined to form a complete roof of a car, thereby dispensing with the necessity of placing a separate running board over the car roof, as is customary with structures of this kind in general use.

A further object is to secure the running board directly on the carlines and providing an improved joint or joints between the running board and the eaves soas ,torender the roof absolutely watertight, and yet sufficiently flexible for all purposes.

A further object is toprovide a roof of this construction which is strong and durable, which is watertight, which is comparatively simple in construction and in its labor of assemblage, and which most efliciently performs the functions for which it is intended. 7 ,With these and'other objects in view, the invention consists in certain novel features of construction and combinations and arhrange'ments of parts which will be more fully hereinafter described and pointed out in the claims. A

In the accompanying drawings Figure 1 is a view mainly in plan but partly broken away to illustrate parts below; a

Figure 2 is an edge view ofthe construc tion shown in Figure 1; Figure 3 1s a view 111 section on the line 33 of Figure 1;

and in design Figure 4 is a fragmentary view in trans verse section on the line 4.4 of Figure l;

Figure 5 is an enlarged fragmentary View in transverse section similar to Figure 4 but showing more clearly in detail the roof structure adjacent the running board;

Figure 6 is aperspective View of one of the cap sheets 9;

Figure 7 is a broken fragmentary view perspective'of one of the roof sheets 5; Figure 8 is a sectional perspective View illustrating a modification; 5

Figures 9 and 10 are views of details of construction shown in Figure 8. My improved roof structure includes any desired number of transversely positioned parallel carlines 1, directly supportin at their center a running board2 and at tieir outer ends secured to side plates 3. On these side plates 3 I locate and secure my improved eave plates ,4: and-locate roof sheets 5 be tween the running board and the eave plates and fitted to both, as will more fully hereinafter appear, and these sheets 5 may be made of any desired size and'at their longitudinal edges are formed with upwar ly projecting flanges or seams 6 between which separator flanges 7' on the cal-lines l project.

Cap bars 8 cover the flanges or seams 6 and the separator flanges 7, and are bolted to the eave plates land the ends of the ear "lines 1, as indicated at 1 1. Cap sheets 9 are located under the cap bars 8 at their inner ends and have upwardly projecting curved ends 12 which correspond in shape with the upwardly curved inner ends 13 of the roof sheets 5 and fit under the depending flanges 14 at the side edges of therunning board 2.

Above the carlines, secured thereto and running longitudinally oft-he car under the roof sheets, I provide any desired number of stringers or purlines 10 which give the necessary support to the roof sheets and strengthen the entire roof structure.

I have set forth generally in the above 7 description the several parts of my improved roof structure which I will now describe more in detail. 7 Y

The running board 2 abo ve referred to, comprises a sheet of proper width and length and having its upper surface roughened, preferably by'the provision of knobs or enlargements and nonslipping material. The

intermediate portions of the carlines 1 dre enlarged vertically so that theirupper flanges 15 provide a horizontal support to which the running board is secured preferably by rivets 16.

The edges of the running board are strengthened by blocks or timbers 17 of any desired length, which are secured by angle bars 18 to the running board, and the depending flanges of the running board are spaced from these timbers or bars 17 sufli cient to accommodate the inner ends of the cap bars 8 as well as the upwardly projecting curved overlapping ends of the roof sheets 5 and the cap plates 9.

The eave plates 4 are throughout their greater portion relatively flat orhorizontal, and at their outer edges have depending flanges 19 which are riveted or otherwlsesecured, as shown at 20, t9 both the plates 3 and the ends of the carlines 1.

The inner edges of the eave plates 4: have upwardly and outwardly bent angular flanges 21, around and under which the outer edges of the roof sheets 5 are curved or projected, as illustrated at 22.

The separator flanges 7 of the carlines 1 are preferably formed integrally with the carlines and project upwardly between the stringers or purlines 10, as clearly shown in Figure 4. 11 Figures 8, 9 and 10, I illustrate a modification in which I employ a flashing strip 23 under laterally projecting side portions of the running board 24, between the runninlg1 board 24 and the bar 17. v I In t is modification I also 'provide cap bars 25 corresponding to the cap bars 8 with upwardly curved ends 26 located under the flange 27 of the running board, and I notch the flashing strip as shown at 28 to accommodate and straddle the upwardly projecting flanges of the roof sheets.

Furthermore, it will be noted that I provide notches 29 in the flanges 27 of the running board to engage over the arched upper .edges of the cap bars 25. This construction provides a prefect watershed and a strong, durable and flexible construction.

Various slight changes and alterations might be made in the general form of the parts described without departing from my invention, and hence I do not. limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:
